GOG have dubbed their latest deal-a-thon ‘Sleepy Sheep’, which must be tricky to enunciate after too many nighttime hours sat watching a PC games storefront. The now-traditional Insomnia Sale is so-called because its deals are artificially limited – and as soon one pile of keys runs out, a different game will pop up at cut-price. There is no rest, no respite, and it’s happening again.

The sale will run from right now until whenever the designated allotment of deals is sold out. The uncontrolled nature of the thing means you can expect new discounts to crop up at unusual points over a 24 hour period.

This time, CD Projekt-run GOG are prepared to include their “crown jewel”, The Witcher 3, at its lowest price to date – $24.99 in the US.

A number of games never before sold on GOG will appear over the coming hours and days. And if you buy 10 games over the course of the sale, you’ll bag an extra one for free.

GOG have been doing this for four years now. Have you ever picked up anything memorable during an Insomnia run?
